ATTACHMENTFOR TYPE -WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 357,271, dated February 8, 1887.

Application filed May 25,1885. Serial No. 166,665.

To all whom it may concern/.-

- Be it known that I, ALBERT B. DICK, re-

siding at' Chicago, in the county of Oookand State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Attachments for Type-Writing Machines, of which the following is a full description, reference being had to the accompanying drawings, in which 7 Figure 1 is a plan View with the paper-carrier thrown up; Fig. 2, a side elevation with the paper-carrier down; Fig. 3, a detail showing amodification in the connection for operating the ribbon-mover; Fig. 4, a perspective view showing the attachment detached from the machine; Fig. 5, a perspective view showing a portion of the frame-work of the ma chine,with the reflector and pointer for indicating purposes; Fig. 6, a detail showing the adjusting-screw for changing the throw of the ribbon-mover to bring an unusual portion in position for use.

The object of this invention is to construct an attachment to be applied to type-writing machinery of the, Remington and caligraph style, for the purpose of enabling the operator to readily discover mistakes and reset the paper carrier to correct mistakes without raising the carrier, as is now the case, and to enable the operator to bring the carrier into position for correcting mistakes, or settinga column of figures or other-like purpose readily and quickly and without the use of the numboring-bars and pointers now used for such purpose, and also to enable the ribbon to be adj usted and held in its adjusted position without liability of changing in the use of the machine; and its nature consists in the several parts and combinations of parts hereinafter described, and pointed out in' the claims as new.

In the drawings, the typewriting machine proper is not shown in detail as to all of its working parts, as only so much of a complete type-writing'machine is shown as is necessary to illustrate the location and operation of the devices pertaining to this invention, and the parts not shown in detail are to be of the usual construction of such parts for a Remington or caligraph typewriting machine.

A represents an arm or support, ofan L' shape, one portion, a, standing vertical, and

(NomodeLl the other portion, a, horizontal, or nearly so, when the arm or support is in position on the machine. This arm maybe made of iron,brass, or other suitable material, and an arm is to be provided'for each side of the machinc,both arms being similarin construction,as shown in Fig. 4.

B is a fork on the upper end of each arm or support A, and is of sufficient width for the width of ribbon used on the machine, the ribbon running over a cross-bar, b,in the ends of the fork-arm, as shown in Fig. 4, with an anti-friction roller. I

O is a lever pivotally connected "at one end to the portion a of the arm or support A by a suitable screw or pivot, c, a lever, G, being connected to each arm or support A, and the outer ends of the levers O are connected by a cross-piece,0, in the form of construction where the operation of the ribbon-mover is not to be automatic with that of the type and spacers, and where the ribbon-mover is actuated independent of the writing mechanism; but where the ribbon-mover is to be operated automatically by the movement of the type and spacer devicesa connecting-bar,-Q, is provided, as shown in Fig. 3, connectingthe lever C with the lever-frame of the type-writer.

D is a cross-rod running from arm to arm A, and forming apivotal support for the arms, the arms being held in place in the form of construction shown by a nut, d, on the end of the rod D.

E is a reflector formed of two reflecting-surfaces, standing -'at the proper angle in relation to each other to throw the reflection from one side onto the opposite side. This reflector is located on the cross-rod D, and, as shown, is held in position by brackets or supports E, clasped or socketed onto the rod, and having ears e,which receive and retain the reflectingsurfaces, as shown in Fig. 4:. This reflector is located directly underneath the paper cylinder or carrier when down, so that the line of writing on the paper will be received by the front reflecting-surface and thrown onto the rear reflecting-surface, where it is visible to the operator without raising the paper-carrier.

F are brackets attached by screws or otherwise to the frame work of the machine, as shown in Fig. 2, and in which the rod Dis supported. 1

G are brackets or supports, one on each side of the bed-plate of the machine, and to which the arms 0 are pivoted by suitable pins or pivots, c. As shown, the brackets F are attached to the cross-bar of the machine by passing a set-screw through a hole, f, in the turned end of the bracket to enter the cross-piece of the frame, and the supports G are attached to the side pieces of the base by screws g, and the location of these brackets F G is one to furnish a support for the rod D and reflector E and arms or levers A, and also a support for the lever C in its relation to the arm or lever A.

H is a standard attached to the top of the base, as shown in Figs. 1 and 2, and carrying an adjusting-screw, 71, the end of which engages the; arm or lever O and limits the upward movement of such arm or lever at its rear end, by which a limit of movement for the upper end of the arms or leversAis furnished to change the position of the ribbon in rela tion to the striking line of the type, so that when the ribbon is worn out at one place it can be shifted to bring a new place into position and be maintained in the direct line of run for the new place to receive the striking type.

I is a pointer attached to the front bar of the upper frame-work, as shown in Fig. 5, so as to stand at the center of the machine and in line with the point where each type strikes, and this pointer is reflected by the reflector E, so as to be visible to the operator in connection with the line of writing, by which the operator can tell exactly when a misprinted letter or the plate for an unstruck letter is brought into proper'posit-ion to be reprinted, or so that the operator can tell exactly at what position to set his carrier to bring a column of figures in proper position for the aligning of the units, tens, 8:0.

The drawings do not show the keys, typerod, or type, these parts being omitted, as they are not necessary to illustrate the invention and of the parts shown J represents the space-keys, through which the spacing-frame K is actuated,as usual, and when the attachment is made automatic the bar G is pivoted at c to the lever O, and at c to the spacing-frame K, as shown in Fig. 3, so that'at each movement of the space-keys or type-keys the ribbon will be shifted in its position, as hereinafter described.

The connection 0 may be used on one side or on both sides, as may be desired, and the bar G, when used, causes both sides of the attachment to work simultaneously, so as to insure a movement of both sides to carry the ribbon out of the way or bring it back into position at the same time. g

In use the attachment is applied to the typewriter by attaching the brackets F to the crossbar of the upright portion of the frame by a screw or otherwise,and by attaching the brackets G to the side of the base of the frame by screws or otherwise. The rod D,with the refleetor E thereon, is slipped into the brackets or supports F, with the ends of the rod projecting beyond the bracket to receive the uprights or arms A, which are secured thereon in a pivotal manner by nuts (I, or in some other suitable manner, the brackets F being located so as to bring the reflector in proper position in relation to the paper-carrier to receive the reflection of the letters on the paper on the front reflecting'surface and transfer it to the rear reflecting-surface, which stands at the proper angle for the operator to look down thereon without raising the paper-carrier and see what work is being done.

The lever 0, when arranged as shown in Fig. 2, has its front end pivoted to the end of the arm a and pivotally connected to the bracket G, with its rear end extending back to receive the cross-bar C, and when arranged as shown in Fig. 3 the rear portion is omitted, and the connecting-bar Ois attached forward of the pivotal point of thelever to the bracket. \Vith the arrangement shown in Fig. 2 the operator, by pressing down on the bar O,carries down the rear end of the lever 0, raising the front end of such lever, and also the end of the arm a, which movement carries backward the upper end of the arm A, with the fork B,

throwing the arm and' fork, with the impression-ribbon, backward in the position shown in dotted lines in Fig. 2, leaving a clear space for the operator to make observations of what is shownin the reflector E, so as to distinguish whether the work is being done properly, and if corrections are needed to make them. \Vith the arrangement shown in Fig. 3 each downward movement of the space-keys or of the type-keys throws down the spacing-frame K, as usual, and such downward movement of the spacing-frame carries down the forward ends of the lever G, and with it the end of the portion a of the arm A, bringing the upper end of the arm A, with the fork, into the position shown by the full lines in Fig. 2, it being understood that when the parts are at rest the arm and fork are in the position shown by the dotted lines in Fig. 2, and with this form of construction the ribbon, when the parts are at rest, is in the position for the operator to view the reflector; but when the machine is in use the ribbonis brought into position to be struck by the type with each movement of the typekeys. The operator, by viewing the reflector E, observes therein the reflection of the arrow or pointer I, and as this pointer is located at the center line, where each type strikes, it will be seen that the operator can at once tell when the carrier has been set at the proper point for any desired letter to be thrown up to make an impression, or at the proper point to bring a column of figures or other matter properly in alignment.

The attachment as a whole is very simple, and can be applied to either aRemington, caligiaph, or other type-spacing machine similar in construction without changing any of the parts of such type-spacing machine, except to remove the adjusting-bar with the numer- I als thereon now used for setting the carrier,

which is not'neededwith thepointer I, and the attachment when complete will not interfere in any manner with the use of the typewriter, and by providing the arm or bracket 11 with the adjusting-screw h, to bear on the end of the lever O, the movement of the upper end of the arm A can be adjusted to bring the impression-ribbon into position for use on any desired line, so that when one portion of the ribbon becomes worn out a new portion can be brought into position for use and be held in a straight line.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a type-writing machine, of the L-shaped arms A, located at each side thereof and pivotally connected therewith,

I and carrying at the upper ends of the vertical portions the impression-ribbon, and means, substantially as described,connectedwith the horizontal portions of said arms for operating the same and moving the ribbon into and out of line, substantially as specified.

2. The combination, in a type-writing machine, of the L-shaped arms A, carrying the impression-ribbon at their upper ends and pivotally supported on the frame of the machine, the lever O, pivota-lly connected with the horizontal portions of the arms A and with brackets G, secured to the frame of the machine, and the cross-bar O, substantially as and for the purpose described.

3. The combination, in a type-writing machine, of the L-shaped arms A, carrying the impression ribbon' at their upper ends, and pivotallysupported on the frame of the machine, the levers O, pivotaily connected with the horizontal portions of the arms A and with brackets G, secured to the frame of the machine, and the connecting-bar 0, connected with the levers G and with the spacing'frame -K, substantially as and for the purpose described.

4. The L-shaped arms A, pivotally connected with the frame of the machine at opposite sides thereof, forked at their upper extremities and carrying the impression-ribbon, substantially as described.

5. In a type-writing machine,the double mirror, attached and arranged substantially as described and shown, whereby the line of writing on the paper will be received by the front reflecting surface, and from thence thrown on the rear reflecting-surface, so as to be seen by the operator, substantiallyas described.

6. In a type-writing machine, the double mirror, attached and arranged substantially as described and shown, in combination with the pointer I, located above the reflector and secured to the front bar of the upper frame work at the center of .the machine, whereby theline of writing and the image of the pointer will'be received by the front reflecting-surface, and from thence thrown on the rear reflectingsurface, so as to be seen by the operator, substantially as described.

7. The combination, with the carrier-arm.A and lever G, of an adjusting-screw for regulating the throw of the arm A to adjust the ribbon, substantially as and for the purpose specified.
